London (CNN) -- Call them the minor royals.
They rarely make the front pages of the tabloids and you might not even be aware that they exist, but they all belong to the House of Windsor.
Their status means these lesser-known members of the royal family will be among the roughly 1,900 guests at Prince William and Kate Middleton's wedding.
David and Serena Armstrong-Jones, Viscount and Viscountess Linley
Born: 1961 and 1970
Viscount Linley is the first cousin once removed of Princes William and Harry, son of the Queen's late sister Margaret and Anthony Armstrong-Jones, the Earl of Snowdon. He is 14th in line to the throne. A handy chap, he has his own bespoke furniture design company. He married Serena Stanhope in 1993, with whom he has two children -- Charles and Margarita. Margarita will be a bridesmaid at William and Kate's wedding.
Lady Sarah Chatto
First cousin once removed of Princes William and Harry, sister to Viscount Linley and daughter of the Queen's late sister Margaret. Lady Sarah, an artist, is 17th in line to the throne. She married Daniel Chatto, an artist and former actor, in 1994 and has two children, Samuel and Arthur.
The Duke and Duchess of Gloucester
Born: 1944 and 1946
The Queen's cousin Prince Richard, Duke of Gloucester has interests in architecture, heritage and fast cars (he was banned from driving for six months for speeding in 2004). He is 20th in line to the throne. His wife, Birgitte, is president of the Royal Academy of Music.
The Duke and Duchess's children, the Earl of Ulster; Lady Davina and Gary Lewis; and Lady Rose and George Gilman will also attend.
The Duke and Duchess of Kent
Born: 1935 and 1933
Prince Edward, Duke of Kent, cousin of the Queen and 28th in line to the throne, is a keen tennis fan and as president of the All England Lawn Tennis and Croquet Club, he presents the trophies at Wimbledon each year. He was the royal family's Special Representative for International Trade and Investment until 2001, when Prince Andrew took over the role. His wife, Katharine, is known for her love of music.
The Duke and Duchess are invited along with their children, the Earl of St. Andrews and family; Lady Helen Taylor and her husband Timothy; and Lord and Lady Nicholas Windsor.
Prince and Princess Michael of Kent
Born: 1942 and 1945
Prince Michael is the Queen's first cousin and a grandson of King George V. In 1978, he married the German-Hungarian Baroness Marie-Christine von Reibnitz, losing his right of succession because his wife was Catholic. Nicknamed in the British press as "Princess Pushy," Princess Michael is keen on history and pens books about racy royals. The Queen had been paying for the couple to reside at Kensington Palace, until the pesky Public Accounts Committee made them cough up the rent.
Lord Frederick Windsor and Sophie Winkleman
Born: 1979 and 1980
Son of Prince and Princess Michael of Kent and first cousin once removed to the queen. Educated at Eton and Oxford, he works for investment bank JP Morgan and is 37th in line to the throne. In 2009 he married actress Sophie Winkleman -- best known for her role as upper-class love interest Big Suze in British TV comedy "Peep Show." Despite hefty offers from glossy magazines, they refused to let the public get a peep of their wedding day.
